2013-04-26ixgbe: fix EICR write in ixgbe_msix_otherJacob Keller
Previously, the ixgbe_msix_other was writing the full 32bits of the set interrupts, instead of only the ones which the ixgbe_msix_other is handling. This resulted in a loss of performance when the X540's PPS feature is enabled due to sometimes clearing queue interrupts which resulted in the driver not getting the interrupt for cleaning the q_vector rings often enough. The fix is to simply mask the lower 16bits off so that this handler does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal.

2013-04-25net/cpsw: fix irq_disable() with threaded interruptsSebastian Siewior
During high throughput it is likely that we receive both: an RX and TX interrupt. The normal behaviour is that once we enter the ISR the interrupts are disabled in the IRQ chip and so the ISR is invoked only once and the interrupt line is disabled once. It will be re-enabled after napi completes. With threaded interrupts on the other hand the interrupt the interrupt is disabled immediately and the ISR is marked for "later". By having TX and RX interrupt marked pending we invoke them both and disable the interrupt line twice. The napi callback is still executed once and so after it completes we remain with interrupts disabled. The initial patch simply removed the cpsw_{enable|disable}_irq() calls and it worked well on my AM335X ES1.0 (beagle bone). On ES2.0 (beagle bone black) it caused an never ending interrupt (even after the mask via cpsw_intr_disable()) according to Mugunthan V N. Since I don't have the ES2.0 and no idea what is going on this patch tracks the state of the irq_disable() call and execute it only when not yet done. The book keeping is done on the first struct since with dual_emac we can have two of those and only one interrupt line.

2013-04-25net/cpsw: redo rx skb allocation in rx pathSebastian Siewior
In case that we run into OOM during the allocation of the new rx-skb we don't get one and we have one skb less than we used to have. If this continues to happen then we end up with no rx-skbs at all. This patch changes the following: - if we fail to allocate the new skb, then we treat the currently completed skb as the new one and so drop the currently received data. - instead of testing multiple times if the device is gone we rely one the status field which is set to -ENOSYS in case the channel is going down and incomplete requests are purged. cpdma_chan_stop() removes most of the packages with -ENOSYS. The currently active packet which is removed has the "tear down" bit set. So if that bit is set, we send ENOSYS as well otherwise we pass the status bits which are required to figure out which of the two possible just finished.

2013-04-25net/cpsw: don't rely only on netif_running() to check which device is activeSebastian Siewior
netif_running() reports false before the ->ndo_stop() callback is called. That means if one executes "ifconfig down" and the system receives an interrupt before the interrupt source has been disabled we hang for always for two reasons: - we never disable the interrupt source because devices claim to be already inactive and don't feel responsible. - since the ISR always reports IRQ_HANDLED the line is never deactivated because it looks like the ISR feels responsible. This patch changes the logic in the ISR a little: - If none of the status registers reports an active source (RX or TX, misc is ignored because it is not actived) we leave with IRQ_NONE. - the interrupt is deactivated - The first active network device is taken and napi is scheduled. If none are active (a small race window between ndo_down() and the interrupt the) then we leave and should not come back because the source is off. There is no need to schedule the second NAPI because both share the same dma queue.

2013-04-25net/cpsw: don't continue if we miss to allocate rx skbsSebastian Siewior
if during "ifconfig up" we run out of mem we continue regardless how many skbs we got. In worst case we have zero RX skbs and can't ever receive further packets since the RX skbs are never reallocated. If cpdma_chan_submit() fails we even leak the skb. This patch changes the behavior here: If we fail to allocate an skb during bring up we don't continue and report that error. Same goes for errors from cpdma_chan_submit(). While here I changed to __netdev_alloc_skb_ip_align() so GFP_KERNEL can be used.

2013-04-25bnx2x: Prevent NULL pointer dereference in kdumpYuval Mintz
In scenarios in which a previous driver was removed without proper cleanup (e.g., kdump), it is possible for the chip to generate an interrupt without any apparent reason once interrupts are requested. Due to an erroneous initialization of resources, some of the bnx2x structs which are required for interrupt handling are initialized only after an interface's interrupt is requested from the OS. As a result, once such a spurious interrupt occurs, it will cause a NULL pointer dereference - the driver will access those structs in its interrupt handling routine. This patch change the interrupt request scheme so that bnx2x would only request interrupts from the kernel after it has finished initializing all the inner structs required for interrupt handling.

2013-04-25sfc: Fix naming of MTD partitions for FPGA bitfilesBen Hutchings
efx_mcdi_get_board_cfg() uses a buffer for the firmware response that is only large enough to hold subtypes for the originally defined set of NVRAM partitions. Longer responses are truncated, and we may read off the end of the buffer when copying out subtypes for additional partitions. In particular, this can result in the MTD partition for an FPGA bitfile being named e.g. 'eth5 sfc_fpga:00' when it should be 'eth5 sfc_fpga:01'. This means the firmware update tool (sfupdate) can't tell which bitfile should be written to the partition. Correct the response buffer size.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== This series contains updates to ixgbe, igb and pci. The ixgbe changes contains a fix to a possible divide by zero by bailing out of the ixgbe_update_itr() function if the last interrupt timeslice is zero. In addition, support is added for the new OCP x520 adapter as well as LX support for 82599 devices. Jacob provides a patch to change variable wol_supported to wol_enabled to better reflect what the code is actually doing (i.e. checking if WoL is enabled). Alex adds SRIOV helper function to pci that will determine if a PF has any VFs that are currently assigned to a guest. The remaining 8 patches are against igb and contain the following changes: * implement SERDES loopback configuration for i210 devices by unsetting sigdetect bit, so as to fix Ethtool loopback test failure * add support for the SMBI semaphore for I210/I211 devices * implement the new generic pci_vfs_assigned helper function (Alex's PCI helper function) * display warning when link speed is downgraded due to Smartspeed * ensure that VLAN hardware filtering remains enabled when the device is in promiscuous mode and VT mode simultaneously * cleanup dead code in igb * bump the driver version v2: updated the PCI patch to add SRIOV helper function to remove extern from the declaration of pci_vfs_assigned in pci.h and return 0 if SR-IOV is disabled which is inline with other PCI SR-IOV functions ==================== Signed-off-by: David S.

2013-04-25igb: SERDES loopback sigdetect bit on i210 devicesAkeem G. Abodunrin
This patch implements SERDES loopback configuration for i210 devices by unsetting sigdetect bit, so as to fix Ethtool loopback test failure. Old sigdetect code is also simplified to take care of all devices newer than 82580 Signed-off-by: Akeem G Abodunrin <akeem.g.abodunrin@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2013-04-25ixgbe: add SFP+ LX module supportDon Skidmore
This patch adds LX support to 82599 devices. This is an alternate patch to the one suggested by Stefan Behte <s.behte@babiel.com> In addition this patch includes some cleanups such as: - removed parenthesis around "x == y ||" lines inside an if statement for consistency. - grouped the sx/lx sfp types along with srlr in ixgbe_get_settings() since they all have the same supported, advertised and port values.

2013-04-25ixgbe: rename wol_supported to more fitting wol_enabledJacob Keller
The variable wol_supported really is just checking whether it is enabled, rather than whether it is supported. If it is enabled it will be supported, but this does not necessarily hold true the other way around. This patch renames the variable to avoid confusion.
